The system administrator has set policies to prevent this installation

I've made some changes to my product, not installation related at all, just changed which libs do I use for non installation related issues and suddenly I have this weird msg popping up whenever I try to install.
"The system administrator has set policies to prevent this installation"

Previous versions/builds (even with the same version number) install fine.
This is the output of the verbose logging:

Change this value to 1 - to disable the Administrator only install a.k.a
anyone can do it.

If all fails .... The system Administrator has set policies
to prevent this installation,,,,, ensure you are logged on as Administrator
or any Administrative User privileges or Right click setup.exe and Run As Administrator
